An implmentation of the classical sequence analysis workflow:
Find homologues (sequence similarity search)
Fetch homologues
Align homologues (multiple sequence alignment)
Produce phylogenetic tree
In this implementation the EBI webservices are used:
WU-BLAST (WSWUBlast) blastp vs. UniProtKB
dbfetch (WSDbfetch)
ClustalW (WSClustalW2)
ClustalW (WSClustalW2)
Note: this version does not add the inital query sequence to the alignment, and so is most useful when used with the identifers...
